UNiTnD- STATES PATENT 'OFFICE' SAMUEL DANIELS, CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO MELVILLE E. DAYTON, OF SAME PLACE.

BURNER FOR GAS OR VAPOR STOVES.

SPECIFICATION forming part of Letters Patent No. 377,547, dated February 7,` 1888.

Applicationled J' une B. 1885. Serial No. 167,973. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, SAMUEnDANIELs, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lmprovements'in Burners for Gas or Vapor Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to burners for gas or vapor; and it has for its object to produce an annu-lar dame and one which it will not be easy to extinguish by blowing thereon or into the orifice of the burner.

-junets shown in Fig. 1.

The invention is shown as part of a hydrocarbon-vapor-generating burner, in which the advantage last mentioned is more important, for the reason that the vapor-flame of' such burners, as commonly constructed, is very easily extinguished by a wind or sudden puff of air into the orifice, while the results of such extnguishment of the flame may be seriously.

disastrous in allowing the escape of hydrocarbon liquid at the needle-valve.

The said invention will be best understood from the followingdescription and the accompanying drawings, in which-- r Figure l is a central vertical section of the burner shown in a construction adapted for the generation of hydrocarbon vapor. Fig.v 2 is a plan view of the burner and of the ad- Fig. 3 is a vertical central section of the burner proper applied to a support, (shown in dotted lines,) which support has a central orifice for the admission either of gas or of hydrocarbon vapor, this figure being intended toillustrate the applil cability of such burner proper to either gas stoves or to the base-plate ofa style of'hydrocarbon-vapor burners now commonly in use. In said Fig. 3 is also shown a modification of' the interior cylinder or ring by which the two circular plates of the burner are supported at a proper distance apart. Fig. 4 is a perspective View of a preferred form of the central cylinder or ring by which the two circular plates of the burner are held apart in proper position, the said ring being provided with annular throngh-grooves for the outward passage of the gas or vapor.

A represents a circular base-plate of shallow cup shape and having a central orifice or opening, ct, surrounded by an annular upwardly-direeted vertical iiange, a.

Bis a similar cupshaped disk, preferably somewhat larger than the disk A, and supported in an inverted position over the latter, as shown. The disk B is provided with a depending annular and concentric flange b,. which, in the completed burner, stands oppo-4 site the flange a of the lower disk, A.

C is a ring, preferably cylindric in form, intended to rest on the lower plate, A, and to support therefrom the upper plate, B, at such a distance as to afford the annular passage d,

between the edges of the flanges a and b, and also the annular passage D, between the edges of the disks A and B, for the emission of the vapor in a circular sheet, and to produce from such vapor, when ignited, an annular flame external to the margin of the said disks. The

said ring C is provided'with two horizontal parallel passages, c c, for the outward movement of the gas orvapor from the passage d to the passage D. I prefer to construct the ring C in the particular manner clearly shown in Figs. l and 4, wherein it is shown as a separate cylindric casting,having a series of interior vertical ribs, c', and ,wherein the horizontal and parallel passages c o are made by cutting inwardly from the outer surface of said ring through the body of the ring toor into the vertical studs c', so as to make said passages practically continuous. Said ring G may, however, be less advantageously constructed with the ribs or studs c projecting above and below the central body of the ring, and thereby afford passages c c directly between said body of the ring and the upper and lower plates of the burner, as shown in Fig. 3. This last-mentioned construction is less calculated to protect the burner opening D might in that-case pass along they surfaces of the burner-plates A and B and enter said openings c, while in the constructionV IOO of Fig. 1 such current will strike the narrow rings between the passages c and the burnerplates and thus be arrested or deflected. It is also practicable and, perhaps, desirable, to cast the ring C integrally .with or as part of one of the plates A B, in which case the annular through-grooves c c may be cut in the same way described, or by means of a turningtool, in the same relative positions illustrated in Figs. l and 4.

When the ring C is a separate piece, it will be held concentrically with the several burnerplates A and B by means of the iianges a and b, which will be cast on said burner-plates of such size as to lit within the ring-studs c', as shown in Figs. l, 2, and The presence'of the interior studs or ribs, c', affords an annular space, D', between the ring and the flanges a and b, into which the gas or vapor first passes from the opening d, and from which it emerges through the passages c c into the outer space, d', between the bni'nerplates. It will` be observed that, as illustrated in the drawings, the passage d is located centrally or about midway between the plates A and B, and also that the passage D is substantially inthe same plane with the passage d, while the passages c and c are located one above and one below said central plane. The result of this preferable arrangement of said passages is that the stream of gas or Vapor, after leaving the passage d, is broken up into two bodies, which pass ont separately through the passages o c, and finally emerge through the outer annular opening, D. In the case of a vapor with which air is to be eommingled, as inthe ease of hydrocarbon vapor, this breaking up and remixing of the fluid, together with the deflections of its course through the burner,

operates to produce a thorough coinmingling of the air with the Vapor and to thereby insure proper combustion and an exceptional steadiness and strength of flame. By reason, also, of the fact that the passages c c are located out of the plane of the outer passage, D, a puff of wind blowing horizontally inte said outer passage, D, will not readily enter either of the said passages c, but will rather, in most eases, impinge against the body ofthe ring between said passages; and if the current of such windpuit be directed upwardly or downwardly only it will not interfere with the egress of vapor from the passage not in line with said current.

' By this means the construction described renders the extinguishment of the flame dicult when the burner is in operation.

Whether the ring C be cast as a separate piece, as shown, or as part of one of the burnerplates, the flanges a' b, or one of them, being fitted to freely but rather accurately enter between the ribs c', as set forth, enables the burner to be quickly and reliably put together' or to be taken apart for any purpose.

Vhen the burner is intended for generating as well as burning hydrocarbon vapor, the lower burner-plate, A, will desirably be cast with provisions for conducting the hydrocarbon liquid into position to be vaporized. Such a construction is shown in Figs. 1 and 2, wherein the said burner-plate is cast with connected and cored arms A A2, arranged in proper positions, one to admit liquid and the other to conduct the vapor tothe needle-valve, in a familiar manner.

In Fig. 3the centrally-apertured base-plate E (shown in dottedlines) represents a familiar form of base-plate now commonly in use in hydrocarbon vapor burners, to which ordinarily is applied a removable perforated cap, which rests on said base-plate. rlhe present bnrneris shown provided with a bottom flange, a2, adapted to fit the base-plate E', in place ot' said perforated cap, and so as to bring the oriiiee a ofthe burner-plate A concentrieally over that of the baseplate E. This construction enables the present burner to be conveniently substituted for the said ordinary perforated cap.

The construction rof the slotted burneivring vC, having its parts connected by interior ribs transverse to the slots and integral with said parts ofthe ring, will form the subject of another application for patent, and is herein claimed only in combination with the disks A and B.

I claim as my inventionl. rllhe burner consisting, essentially, of two cup-shaped disks, A and B, provided, respectively, with opposing iianges a Z1, and having their edges and said flanges separated at D and d, and a ring, C, interposed between the disks in position to afford a space, D', exterior to the flanges a b, and having passages at c c out of the plane of the opening D, substantially as and for the purposes set forth.

2. The combination, with the burner-plates A and B, provided, respectively, with opposing flanges a b, of a ring, C, provided with interior'ribs, c', and continuous slots c c, suhstantially as described.

3. The burner composed of the separate opposing flanged disks A and B and interposed ring C, substantially as described, the lower disk being provided with an annular flange, c2, whereby the burner is adapted to be applied to a base-plate, F/, substantially as stated.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
